Created attachment 176591 [details] Project file I was working normally on this project yesterday. But today everytime I open the project and click on a subtitle clip on the timeline to edit it, Kdenlive crashes. This happens either on the Debian repository version or in the Appimage. I'm attaching my project file and below is what I get from the debug: "[Thread 0x7ffe30ff96c0 (LWP 29236) exited] qml: ENTER MOUSE END AREA qml: ENTER MOUSE END AREA qml: ENTERED SUBTITLE MOUSE AREA qml: ENTER MOUSE END AREA qml: ENTERED SUBTITLE MOUSE AREA qml: ENTERED ITEM CLCKD: Even though the pipeline has gone through in the Witsuwatin territory, I see so many successes in ID: 3591 START FRM: 5527 ::: REQUESTING SELECTION CLEAR!!!!!! ::: SHOWING SUBTITLE: 3591 terminate called after throwing an instance of 'std::out_of_range' what(): map::at Thread 1 "kdenlive" received signal SIGABRT, Aborted. __pthread_kill_implementation (threadid=<optimized out>, signo=signo@entry=6, no_tid=no_tid@entry=0) at ./nptl/pthread_kill.c:44 warning: 44 ./nptl/pthread_kill.c: Arquivo ou diretório inexistente (gdb) "

The crash log shows nothing related to Kdenlive. It seems your project get corrupted. Please open a backup file. Project -> Open Backup File -> choose an older version. Does an older project file works?

Project -> > Open Backup File -> choose an older version. Does an older project file > works? An older project works apparently seems to be working. But weirdly I cannot copy and paste the clips from the newest project to the older. It keeps saying it's not possible even though I tried to paste it on a new sequence with more than enough empty tracks. I don't know what you mean about the crash log doesn't showing nothing related to Kdenlive. I followed the instructions on https://kdenlive.org/en/bug-reports/ and the document I attached here is the output of "thread apply all bt full" and it contains tons of "kdenlive" threads.
